A usability test was performed for a 3D virtual liver surgical planning system, named Dr. Liver. The system consists of five modules including (1) (1) Liver Extraction, (2) Vessel Extraction, (3) Tumor Extraction, (4) Liver Segmentation, and (5) Liver Surgery Planning. Various performance and preference measures were applied and opinions of the participants regarding likes, dislikes, and suggestions were collected. Three medical doctors participated in the usability test, consisting of five test modules. The system received a high score of satisfaction (mean = 6.5, S.D. = 0.8) as measured using a 7-point Likert scale throughout the five test modules. Based on the evaluation results, recommendations were made for better usability of the system. The present study would help practitioners to evaluate the usability of a system and identify potential usability problems in a systematic manner.
